Towards an Optimal Network Topology in Wireless Sensor Networks

As the demand for wireless sensor networks increases in both military and civilian sector, the need for a stable networking scheme has increased. Wireless sensor network, or WSN, must be robust networks capable of handling many adverse conditions. If these adverse conditions cannot be handled effectively they can result in data loss and under extreme conditions total network failure. Through the use of a hybrid network topology, WSN can be stable and reliable throughout the life of the node. The paper introduces the new proposed network topology in a WSN environment called leader-based enhanced butterfly (LEB) network which is based on our previous work, enhanced butterfly network. The proposed network guarantees the maximum reaching steps of n+1 in the ⎣2⋅2⎦ nodes. And also, in order to demonstrate the nodes behaviors in the network, Petri net modeling and simulation are conducted and showed the soundness of the network.
